TPA6211A1 SLOS367B – AUGUST 2003 – REVISED AUGUST 2004 3.1-W MONO FULLY DIFFERENTIAL AUDIO POWER AMPLIFIER • Ideal for Wireless Handsets, PDAs, and • Designed for Wireless or Cellular Handsets Notebook Computers and PDAs • 3.1 W Into 3 Ω From a 5-V Supply at THD = 10% (Typ) The TPA6211A1 is a 3.1-W mono fully-differential • Low Supply Current: 4 mA Typ at 5 V amplifier designed to drive a speaker with at least • Shutdown Current: 0.01 µA Typ 3- Ω impedance while consuming only 20 mm2 total • Fast Startup With Minimal Pop printed-circuit board (PCB) area in most applications. The device operates from 2.5 V to 5.5 V, drawing • Only Three External Components only 4 mA of quiescent supply current. The – Improved PSRR (-80 dB) and Wide Supply TPA6211A1 is available in the space-saving Voltage (2.5 V to 5.5 V) for Direct Battery 3-mm × 3-mm QFN (DRB) and the 8-pin MSOP Operation (DGN) PowerPAD™ packages. – Fully Differential Design Reduces RF Features like -80 dB supply voltage rejection from Rectification 20 Hz to 2 kHz, improved RF rectification immunity, – -63 dB CMRR Eliminates Two Input small PCB area, and a fast startup with minimal pop Coupling Capacitors makes the TPA6211A1 ideal for PDA/smart phone applications.
